Be it known that we, AUons'rUs S. Wnrrn war and Jossru- SULLIVAN,citizens of the l'nited States, residing at Boise, in. the.

county of Ada and State of ldaho, have -inveuted a neWand uset'ulIntegral Curb and Gutter and, Means for Installing Same, of which thefollowing is a ,specitic,ation..

The object of our invention is to provide 10 a novel integral curb andgutter of concrete; to. provide novel and economical means forinstalling same; and to provide novel means for erecting, adjusting andremoving a combined curb and gutter. form. It is further our object'toprovide improvementsin the inafter set forth. H h g \Vc attainthe'objects of our invention by the mechanism illustrated m theaccompanying drawings, in which-- t Figure 1 is a front elevation of ourcurb and gutter form viewed .irom the gutter side; Fig. 2 is atransverse section through our integral curb and gutter and the combined curb and gutter form, on line 22 of Fig. 1. the gutter form memberbeing shown in extended position by dotted lines; Fig. 3 is aperspective of curb form member 1; F ig. & is a perspective of gutterform member 2; Fig. 5 is a perspective of expansion joint member3; Fig.6 is a detail sec tional view on line 6(5 of Fig. 2; Fig. 7 is a detailof one of the inner reinforcing plates 14 and countersunk bolts 13; andFig. 8 is a perspective of an extension gutter form member 4 adapted tobe interposed between members 1 anti 2.

Like numerals designate tlniiughout the several views Referring to theaccompanying drawings, we provide an angular gutter form member 1,adapted to adjustably engage with an angular guttcr form member 2 bymeans ot' a suitable bolt 5, inserted through a hori- 45mntally-extending orificed portion. 16 of member 1 and ahorizontally-extending slotted portion 17 of member 2 as shown in Fig.6, or, when a very wide gutter is required, member 1 ma adjustablyengage an angular slotted member 1 by means of bolt. 5, and member 4 inturnengage member 2 by means of a like bolt 5, in similar manner.Suitable planks (5, 7 and 8 are secured to the upwardly converging sides9 and 10 55 of form 1 and 11 off form 2, respectively, byineans ofsuitable bolts 12 and 13 having like parts Application m July 22. 1916.Serial a... 110,747.

their heads countersunk as shownin Fig.2 The. heads of bolts 13 engagein a rein 't'oreing metal plate or strip 14 countersu k in plank T, asillustrated in Fig. 7. On:the{ outer portions of planks 7 .and.8nearfthe' end of each section we provide outeriineti tl" reinforcingplates 15,.as shown in Fig.1; and 2, bolted to the planks. Member lisi'provided with an outtur ned oi'ifi'ced'foot,l,8 and member-2 is provldedwith a sir lar" outturned orificed foot 19. Forms'l and are secured tothe ground byb steel stakes} 20, which are each provided with ahandleportion21 bent at an angle Ora-appear; mately lQOdegrees relative to'th'efbody of' the stake, as illustrated. The'steel" stakes" are onefoot seven inches long with a handle" about six inches in length.suit'afble' iex pansion joint members 3' are provided for each sectionat suitable distances apartin the form, the distanceapart ofjth esemenibers determining the length ofpplanks tor"- torm sections. ,Members3 are provided, with inch orifices 22 for'liftin'g the ex: pansion jointwhen the forms are removed. ()n the outer side of plank 7 is fastened aone inch by one inch wood screed 23 for the purpose of forming the shapeof upper side of gutter. 24 designates the engineers :5 wooden stakes toindicate position for forms. In erecting the forms, engineers level Istakes 24 aredriven in place, and the planks, which are bolted to theiron-forms are rested directly on the engineers stakes, there-,- bycausing the curb and gutter when com.-

pleted to be absolutely level and straight. The adjustable engagement offorms 1 and used for a wide gutter) makes it possible -to readily securethe form in pla'ce at any, u. sual desired width. By reason of the con"-vergent disposition of the sides 9, 10 and 11 of the form members 1 and2, our forms can be lifted and removed easily and Without injury to theconcrete inthe curb and gutter. This construction constitutes a greatadvantage over other forms, as the top of the curb and gutter isfinished before our terms are removed from the concrete s -that thefinished lines are perfect, which is not true of other combined for-ms.Our entire form can be removed in one operation and in whole, and it isthen immediately ready to replace without rebuilding again. Our forms 1and 2 are placed a little over three feet apart, three to each section.They are readily secured .a pla by steel stakes 20, and there is nohau'imering or poundlng of the forms after they have been placedon 'theengineers stakes. Consequently thereis no difficulty in keeping theforms in perfect alinement. The stakes 20 are readily withdrawn by meansof thehandles 21. The partitions or expansion joint members 3 extendfrom the grade line up through and to a point one inch above top of curband gutter. orifices '22 are positioned inthemargin of members 3 tomakepossible the convenient removal of these members after the sectionalforms have been removed, without injury to the concrete. .Members 3 arepreferably of galvanized iron. \Vith .thisform the concrete for bothcurb and gutter is held and formed until the concrete is set, forming,

an integral curb and utter. \Vhen a block i or street is three hun' redfeet long the con- .tractor will require 640 feet of forms and twoworkmen to handle the output of a concrete mixer of eighty cubic yardscapacity,

as against;-elevenworkmen required to'in-- stall the'Same amount of curband gutter by former methods. Also an important s'aving of time iseffected in installing the forms after the engineers level stakes aredriven, as two workmen can place in position one thousand feet of theseforms in nine hours.

ass? AvAaAeLE coe All that is required of our form to set it is to placea chalk line on t-hefouter edge of the 11'011 frame at eachendwhlchgives a perfect alinement longitudinally, and resting the formon the engineers stakes gives the proper alinement for the top of curband gutter and does away with the leveling of ground required with formsheretofore devised. Form sections can easily be length- I ened orshortened if desired,v and their ad- .justability simplifies theconstruction work reatly. 4 What we. claim is:

A combined curb and gutter form, com-' prising curb form members havingupwardly convergent; orificedflsides, horizontally extendingangular armssecured to the,

forms. gutter form members having the side thereof convergent to permitof ready removal of the form from the concrete, a hornzontally extendingangular arm secured to i the gutter form, fastening means fo z securingthe aforesaid arms in the desired ad justed relation, andplanks"pennanently sei cured to the form members.
